Specification of Letters Patent.

To all whom it may concern:

Be it known that I, J Acon FELBEL, citizen of the United States, andresident-of the borough of Manhattan, city of New ,York, in the countyof New York and State of Xew, York, have invented certain new and usefulImprovements in Type-Writing Machines, of which the following is aspecification.

My invention relates to ribbon mechanisms for typewritin machines andhas for its object to provide improved devices of A the class specified.

To these and other ends my invention consists in the featuresofconstruction, combinations of devices and arrangements of partshereinafter described and particularly pointed out in the appendedclaims.

I have shown my invention as applied to a Monarch typewriter but thenature of the invention is'such that it may be readily adapted to otherstyles of writing machines. Two forms of the invention are illustratedin the accompanying drawings wherein- Figure 1 is a vertical front torear sectional view taken about centrally of a typewriting machineshowing my invention em bodied therein, parts of the machine beingomitted. Fig.2 is a fragmentary front elovation of the upperpart of themachine, parts being omitted. view showing certain of the parts of myinvention. Fig. 4 is a horizontal sectional view taken on a planebeneath the top plate of the machine and showing certain features of myinvention and allied parts. The top plate, platen;right-hand ribbonspool and part of the ribbon are shown in dotted lines, being above theplane on which the section is taken. Fig. 4 is an enlarged front view ofthe upright. portion of the ribbon vibrator. Fig. 5 is a viewcorresponding to Fig. 4: but showing a further development of myinvention. Fig. 6 is a transverse vertical sectional view taken on theplane represented by the dotted line I -00 of Fig. 5 and looking in thedirection of the arrows at said line. 7

Referring first to Figs. 1 to t inclusive, the main-frame-'of,-.themachine comprises a base 1, corner -posts- 2' and a top plate 3. Key

Fig. 3 is a PGI'SPBCUVQ The parts thus lower end portion of eachsub-lever is slotted at 9 to cooperate with a fixed abutment 10 and theupper end-of each sub-lever is connected by a link 11 to a type bar 12.The type bars are mounted in hangers 13, said hangers being arranged ina segment of acircle and being secured each by a screw 14; to asegmental type bar su port 15' suitably mounted on the frame of-t emachine. The type bars cooperate with the'front platen 16(diagrammatically illustrated), said platen being mounted in a rier (notshown), said carrier being guided and supported on the usual or suitableguide ways and being connected by a band or strap 17 with a spring drum18 which tends constantly to draw the platen and platen carrier leftwardacross the top late. The leftward movements of the aten carrier andplaten are controlled by t e usual or suitable escapement devices (notshown), certain of said devices being connected by a link 19 with thecentral arm 20-of a' universal bar frame, said frame also comprising. arock shaft 21 and a universal bar 22 and being provided with a restoringspring (not shown). Said universal bar underlies the set of key levers tand is adapted, when one of said key levers is depressed, to cause theescapement devices to operate to permit of a letter space movement ofthe carriage under the influence of the s ring drum 18. far describe arenot novel and a further description thereof is not deemed necessary.- pI A ribbon 235,18 mounted on ribbon spools 2 L arranged above the topplate one at each side of the machine and forward of the platen.

ljsaid shaft but the Fig. 6 and there .designatedwas 33 dependmg fromthe top plate. The shaft 33'is 'eon1 pinions34 and 35.' The, pm1on34 1sso connected with the driving shaft that t ISCOIDPBllGd'lZO turn alwayswith shaft may move endwise'- relatively to the pinion 34 withoutaffecting the latter.

The pinion is so connected withthe spring drum that during the turnuigmovements of .the latter in one direction sa d plnion 35 is compelled toturnwith said spring drum but during the turnin movethou ht 'necessa'ments of said drum in the other irecton the pinion 35, is not afiected.It is not 1; describe the mechanism or feeding t 1e ribbonlongitudinally in greater detail sin:

this mechanism is not novel and 1s 'or'may be substantially the same asthat employed in the Monarch typewriter.

- It will be'understood that each ribbon spool is provided with asimilar gear train to that above descr bed, beginning with the gear 27terminating with the gear 31, and that .the gears 31 are adapted to meshalternately with their cooperating driving pinions 32. These latter arefixed to-the driving shaft 33 in sucha way that when the latter isshifted back and forth endwise one or the other of said. driving pinions32 is rendered operative; 'The to and fro shifting movement of thedriving .shaft may be effected either manuallyv or automatically in anydesired wa ,"suh for example as that employed in the machine to which myinvention is shown as a pplied. But the mechanism for reversing t eautomatically longitudinal feed of the ribbonis not illustrated in thiscase.

Referring'now to the npvel parts of my invention, these comprise avibratory ribbon carrier or guide, which, in the present instance, is inthe form of a-right angled memberhaving an upright arm 36 and aThoriz'ontal arm 37. The upright arm 36 is arranged infront of the paten and at one side, preferably the rightside, of the printing pointthereon. Said arm 1s provlded with two ribbon receiving slots 38 and 39,

= said slots being parallel and oblique and disposed one above and onebelow the printing 3 oint and printing line on the platen. These slots38 and 39 are formed in the v1- brator to provide two parallel andobliquely arranged turning bars or devices marked 38 and 39, but saidturnlng bars or devices may be otherwise formed or provided. These slotsand turnlng bars are inclined at an angle of 45 to the vertical and theu per one lies above a line connecting the ribbon s ools while the lowerone lies below such ine. The ribbon extends from the right-hand s 001'upwardly and inwardly toward the mi dle of the machine, passing in frontof the arm 36 through the slot 38 after which it takes a turn over thespool. The vertical bar 38 the slot 39, after which it takes anotherturn over the bar 39- outwardlyor toward the-"left to the left-hand orthat portion between the slots or turning bars which may be calledtheprinting portionof the ribbon, is of asingle thickness or ply of ribbonand lies close to the platen,

the left edge ofsai printing portion being ust to the right of theprinting point. This arrangement is shown clearly in Fig. 2 whereinoneof the type blocks is indicated in the printing position b a dottedline designated bfy 12". It will seen from an lnspection 0 Fig. 2 thatthe length of the printing portion of the ribbon is such that when thisprinting portion is swung over to cover the printing point by mechanism,presd M and pg fs hm ticglly downward be-j -.11n 1e arm t A t g Wlth theS rmg'drum 18 by dons-smarts: ence orwardly through fmeshing beveledportion of the ribbon,

The. head of the vibrator of the top turningbar, bottom turning bar, andright-hand connecting neck or bar 36, the left hand side of the headbeing entirely cut away or open between the turning bars so that noportion of the head can be struck by the types when the vibrator ismoved sidewisefor the types to strike the ribbon. lyhis upright portion36 is narrow or cut ay 'as'shown in Fig. 2 so that its 'lefthand edgeclears the right-hand edge of the printing portion of the ribbon.- Theupright arm 36 is, as stated, preferably .integral'with the horizontalarm 37, although it will be obvious that this is not essential.-

consists essentially The arm 37 extends rearwardly beneath the top plateand terminates in a collarportion 37, which receives a headed shoulderedscrew 40, the latter enteringa threaded opening in the top plate andserving as a pivot or fulcrum for the carrier. A wire spring 41 iscoile'd around the collar 37 and tends constantly to turn the arm 36 ofthe carrier ri htward awayfrom the printing point an to maintain saidarm and the printing portion of the ribbon in the normal position shownin Fig. 2.

The carrier or guide is adapted to be vi brated or operated .by novelmechamsm which will now be described. This mechanism is supported on aU-shaped bracket 42 which is secured, at the left of thdcarrier arm-orlever arm 37, to the under side of the top plate by headed screws 43.Supportm arms 425 of the bracket extend downwar lower end portionstoward the right to underlie the arm 37. J ournaled in the lower endportions of the arms 42 is a rock shaft 988,562 4 print, the line a willoperate to actuates'aid bell crank and throw the ribbon carrier sidewiseleftward, causing the printing'portion of the ribbon tojcover providedwith a spline Mounted to associate type bars to slide on the rock shaftis a sleeve 46 which th an} annular groove 47 by is provided wi whichthe sleeve is connected withactuating mechanism presently, to bedescribed. The. the printingpoint on the platen.- The er bore of thesleeve i'si' grooved for the passage tent of the leftward movement orthrow-of the ribbon carrier will depend upon the positionn hich the arm48 occupies with relation tolth'e carrier. The parts are so proportionedand arranged that when the arm 48 is positioned as shown in Figs. 1, 3and 4., the carrier will be moved sidewise far to bring the left-handside or of the printingportion of th of the spline 4 5 and the sleeveisthus so connected with the. rock shaft 44 as to be com-' p'elledalways to turn or rock when said shaft is rocked in'a. manner presentlyto be described. The rocking motion of the shaft conveyed to the leverarm 37 by a cylindrieal arm or connecting in'emb a c1 48 which enoughonlyv is 'iixed at its lower end in the sleeve 48' and half portion"eiitends u wardly therefrom As shown ribbon over the printing point.When the "clearly in 19;. 3 the arm or 'pin 48 is split or arm 48 isshifted rear-ward and the spring slotted as indicated at 49, therebyproviding fingers 48 engage with the opening 53 the two spring fingers48. llach of thgse finsame extent of movement communicated to Tithespring fingers 48 are .ithei'n apart and causes movable arms and thatwhen gem is provided the arm 48 through the printing keys will. ofcourse, serve to throw the ribbon carrier a greater distance since thearm, 48. is now -nearer the fulcrum of said carrier, this greater extentbeing su cient to bring the right-hand side or half of theprintingportion of the ribbon over the printing point.

Referring for sliding the sleeve 46 to and fro on the rock shaft 44' andthereby setting the arm or connecting member 48, said meanscoinprises alever 58 provided with a collar 59, said collar receiving a shoulderedpivot screw ()0 which enters a in the under side of the cillar opening51 is connected by a "with a similar circular opening 53 formed inthjexarm 37 nearer the fulcrum or pivot thereof than is the opening 51.When the sleeve 46 is slid rearward on the rock shaft forced toward eachother and enter the slot 52 which is less in widththan the diameter ofthe openings '51 and 53. During the rearward movementof the sleeve-46the fingers 48 traverse the top plate, there y pivoting said leverbeslot 52 until the opening 53 is reached when tween its ends. The leftor inner arm 58 of the" inherent spring in said fingers forces them toengage with or become seated in the opening 53. The construction issuchthat the sleeve 46 and 4 1 the arm or connecting member 48areadaptjecting pins enter the depression or an to be set in either oneof a plurality of groove 47 in the sleeve 46. The right-hand -o erativerelationswith the arm 37 of the or outer arm 58 is shaped as shown inFig. 4 and terminates outside of the right-hand ribbon carrler. The lugsor ledges 50 cooperate with the under side of the arm 37 edge of the topplate, being there provided and serve, as a support for said arm ineither with an upwardly projecting finger piece or of the 'setpositions/of the spring fingers 48. handle 62. It will be understoodthat when 7 Obviously when the rock shaft 44 is turned the parts are inthe relations shown in *ig.

or rocked in thedirection of thearrow in Fig. 2 the ribbon carrier willbe rotated on its pivot 40 toward the printing point. Thisrocking-motion is conveyed from the universal bar frame to the rockshaft by a connection comprising a crank 311K154- pro 4 and it isdesired to position them to secure the longer throw of the ribboncarrier, e ward, thereby'causing the pin 61 to press against the rearwall of the groove 47 and force the sleeve 46 and arm 48 rearward until46 and being handle (32 may be grasped and pulled forvided with a.collar portion 55 which receives the 5 ring fingers 48 enter the openinga}; the rock shaft 44 and is secured thereto by a and t ins iold theparts in the adyusted posiin 56. The crank arm 54 .projects 'horition.-a zonta lly. leftward from-s the rock shaft and From what has been saidit w ll be underits outer end is connected by a link 57 with stood thatI have provided a vibratory r bthe central arm- 20 of the universal barbon mechanism including a ribbon carrier frame. It will be noted thatthe crank arm which is normally at one side of the'print ing 54, therock shaft 44 the sleeve 46 and the point and which is adapted when theprinting keys are operated to be moved one of a plurality ofpredetermined extents lengthwise of the platen or sidewise from-normaposition and thereby to cause the print ng f the ribbonto cover theprinting arm 48 constitute'in e ecta bell crank lever having anelongated pivot and relatively the universal bar 22 is depressed by anyof the key levers 4, when the latter are operated to cause their ngportlon of the ribb tion comprising only and explained may be employedwith a ribprmtin portion of the printing bon having uniformcharacteristics throughout and certain features of my invention can mentor throw. The mech have described, however, for bon different bon ofuniform character to be more thoroughly exhausted than would. asinglethrow mechanism; andthe described mechanism is particularly adated for use with a ribbon having rinting elds or longitudinal stripes.of di for example, as a ribbon having one field of record ink andanother field of copying ink, or one field of one color and anotherfield of adiiferent color. In the drawings thus farparticularlydescribed I have illustrated such 'a two-color ribbon 23, onof the fields a whereof may, for descri tive purposes, be considered'asblack in coibr and the other field I) as red in color. The field a atthe ribbon is shown as normalfy nearer the printing oint than is thefield b and it Wlll be an erstood that when the arts are adjusted to theposition shown in igs. 1, 3 and 4, an actuation of the printing key willcause the field a to cover the printing point. When it is desired tomake use of the field b or red field the handle 69. is pulled forwardand the arm -l.S set in its rearmost position. To return to the use ofthe black field thereafter it is only necessary to push the. handle 62rearward and cause the parts to resume the relations shown in Figs. 1, 3and 4.

Various changes may be made in my invention without departing from thescope thereof. An example of such changes is shown in Figs. 5 and 6 ofthe drawings which figures illustrate a further development of theinvention wherein the throw of the ribbon may be manually variedpredetern'iined extents as in the first described construction and may,alternatively, also be progressively varied a utomaticallyj- In Figs. 5and 6 a vibratory carrier is provided having as in the first instance avertical arm 63 and an integral horizontal arm 64 pivoted at 65. The arm63 is as before provided with parallel and oblique turning bars 66 and67, one above and one below the point, and a ribbon G8 is threadedthrough these slots and wound upon the ribbon spools (not shown). Themechanism for turning the spools and for feeding the ribbonlongitudinally is or may be the same anism which I giving the ribxtentsof throw enables a rib-' tending finger piece erent characteristics,such, or pin 78.

. ed on the ribbon connected therewith 57. The sl ding movements of thesleeve 71 75 are controlled y a lever 73 pivoted on a shouldered screw74. which screws up into I the top plate from the under side. The in- 73is forked as indicated at 75, the forks being provided with so pins 76which enter the groove or de ression 72 in the sleeve 71. The outer enof the lever 73 is provided with an upwardly exor handle 77 and with adownwardly extending conical The left or inner arm of the lever isconnected with one end of a coiled draw spring 79 which extendsrearwardl 80 depending from the top plate. spring 79 tends constantly toull the inner arm of the lever 73 rearward and thereb to slide thesleeve 71 rearward on the rock shaft 44 and force the arm rearward inthe slot 69. In this form of m invention I provide two means for controling the movements of the lever 73 and through said lever the movementsof the sleeve "[1 and are operative alternately or at different times,one of them being automatic and one manually controlled. Referring firstto the automatic means,

this comprises an arm 81 depending from the 10.5

inner arm of the lever 73 and cooperating with the eccentric face 82 ofa controllihg member 83, which ember is slidably mountdriving shaft 83and so aid shaft. The shaft33 may,however, be moved lengthwiseindependently of the. nu-m'iber S3; and said member may be slid alongthe shaft withoutafi'ecting the shaft.- The connection between the twohe ofany desired" character for efl'ectin these results','such', forexample, as a pin an slot connection, the pin or screw 84 bein in anextension or collar portion 85 of said member 83 lengthwise of the shaft33 and receiving the inner end of the screw or in 84.

The collar portion 85 is ormed-with'a circumferential depression 87which receives a forked arm 88 depending the forked arm and collarforming part of the: means for manually controlling the ribbon throw.Said manual controlling means further comprises a slide rod '90 which isarranged beneath the top plate and is slidprojection 85 or projection 70the arm- 70. These means 109 as to always turn with 110 parts, may

'The means foraccomplishing this setting comprises a spring detent 93 secured to theunder side of the top plate by a screw 94 and cooperative withdepressions or notches 95 and 96 formed in the to) of the sl de rod 90.Said slide rod is furt er provided with a finger piece 97 at itsright-hand or outer end. 'To the left of the finger iiece a collar 98 issecured to the slide rod y a pin 99. said collar hein provided with ahorizontal arm 100' exten ing forwardly beneath the top plate and formedwith two depressions 101 and 102, which depressions are adapted tocooperate with the conical pin 78 as will hereinafter be explained. pin103 projects horizontally rearward from the arm 98 and connected withthis pin is the right-hand end of a draw spring 104, said draw springextending leftward parallel with the slide rod 90 and being connected atthe left with a pin 105 projecting rearwardly from the lug 33. Thetendency of the spring 104 is to constantly force the slide rod and themember 83 toward the left.

Referring first to the operation of the means for automatically varyingthe ribbon throw and assuming that the parts are in the relations shownby the full lines in 5 and 6, it will be understood that when a printingkey is operated the universal bar frame will be depressed and'the link57 drawn down, turning the rock shaft 44- and the arm toward the left.This arm or connecting member controls, through the slot 69, thevibratory ribbon carrier or guide and when said arm is moved as justexplained,

the vertically disposed or printing portion of the ribbon to cover theprinting point on the platen, the parts returning to normal position'after the printing operation. It will further be understood that theextent of this throw or movement of the vibrator from normal positionwill depend upon the positionof the arm or connection 70 with respect tothe slot 69. The operating movement of the arm 7 0 is alwayssubstantially the same in extent but its effect on the vibratory ribboncarrier will depend on its position in the The extent of movement ofsaid car ricr will, of course, increase as the. arm or connection 7 0 ismoved from the front to the rear in the slot 69. This movement isautomatically controlled by the member 83. The

Figs.

said guide will be thrown from normal position to a position which willcause $1 in contact with vthe eccentric face 82 of Saltllllenlbl 83.

.eccentricto the-axisof-rotat-ion of said shaft the position of the pin81 and the "lever which carries it will constantly during the movementsof the carriage in one able in the right-hand lug 33" sup orting\springT-Q is constantly acting to maintainbeing the arm The member 83is forced to turn by. the ribbon driving shaft 33 during movements ofthecarriage and platen be varied direction, this direction being .theprinting I e construction in the Monarch machine. As shown in Fig. 5 theleft arm of the lever 73 is in its extreme forward positionv and theconnecting member 70 is atthe forward end of the slot 69. Consequentlyif a printin key were actuated the vibratory carrier wifi directionpreferably and according to th receive the least extent of movement ofwhich it is capable under proper o enation. Gradually, however, duringsu sequent printing operations, the ribbon driving shaft will be turnedand that portion of the eccentric face 82 which is of greatest radiuswill pass oiit of engagement wi h the pin. 81, permitting the drawspring 73 to draw the sleeve 71* and the connection 70 rearward untilfinally said connection reaches the rear end of the slot 69, after whichit will be gradually forced forward again by the eccentric face 82 andits cotiperat-ing pin 81, the pin always riding against the eccentricface. The result will be that the throw of the vibratory carrier orguide will be progressively varied between its least and greatest limitsand vice versa and the path followed by the type impressions on theribbon will be in a serpentine line which curves back and forth from oneedge of the ribbon to the other. With the autoinaticall varyingmechanism in operation itis isua to employ a ribbon of uniformcharacteristics and have shown such a ribbon 68 in Figs. 5 and 6. Aribbon havin fields of different characteristics, such or example, asthe two color ribbon 23 might, of course be employed with the secondform of th invention when the latter is arranged as hereinbeforedescribed, if variegated or fancy printing be desired. Usually, ofcourse, when a. two-color ribbon'is employed. it-is desired to writewith one color or the other at will and accordingly I'provide meansfordispensing with the automatic progressive which variation results in anauto-- tents to enable one ribbon field or the other 1 to be used.Assuming that the two-color ribbon is in place in the-machine and thatthe partsare in the relationsshownm F1 5 and e, and further that it elsired to make use of the field of the ribbon nearer the printing point,-the operator grasps the button 97 and pulls the slide rod 90 toward theright or outward until the detent 93, disengaging .fromthe notch 95,engages with the notch 96. This causes the guide arm 88 to pull themember 83 rightward and move the eccentric face 82' out of engagementwith the pin 81 as shown by the dotted lines in Fig.5. The rightwardmovement of the slide rod also moves the arm 100 rightward to the dottedline position shown in Fig. 5 and .bringsthe depressions 101 and- 102 insaid arm into the path of movement of the conical pin 78. The rightwardmovement of the slide rod 90 having been completed, the handle 77 may beused to seat the pin 78 in the depression 101. WVhen the pinanddepression are interseated the lever 7 3 will be in the positionshown in full lines in Fig. 5 and consequently the parts will beset tocause the least or shortest throw of the vibratory carrier, bringing theribbon field at the left-hand side of the printing portion of the ribboninto operation. The friction between the pin 7 8 and the depression101', due to the resilience of the outer arm of thQlever 73 issuflicient to overcome the tension of thezspring 7 9. Then it is desiredto make use of the other side or half of the printing portioii foi theribbQD thev parts may be set for this-purpose by pulling the handle 7?forward until the pin 7 S, disengaging from the depression 101, becomesseated in the depression 102. This resetting of the lever 73 forces thesleeve 71 and pin 7 O rearward until said pin is in position tocooperate with the rear end ortion 'ot the slot 69 and consequentlyto-give the ribbon carrier its greatest throw. When it is againdesired'to'make use of the automatic means for varying theribbon throwthe finger piece 97 may be pushed inward'until the detent 93' reengageswith the notch 95 or the handle 77 may be raised to disengage the pin 78from the arm 100 whereupon the spring 104 will pull the rod 90 back to aposition where the detent 93 will engage the notch 95, this movement ofthe rod being limited by a stop 90, Which abuts the right-hand face ofthe lug 33. This inward movement of the rod 90 brings the pin 81 againinto proper relationship to the eccentric face 82. If the change be madewhen the pin 78 is seated in the depression 102, the return or inwardmovement of the rod 90, carrying with it as it does the eccentric, willcause the cone-shaped portion 83 of the member 83 to cam forwardly thepin or arm 81 and thus automatically bring it into proper relationshipwith the eccentric face of said member and restore the'parts to thecondition shown at Fig. 5.

ward movement of the slide rod 90 carries as the eign and-it is one ofthe main to cover the printing point when the print- The leftward orinthe arm 100 out of the path of said pin 78 s" normal position of thevibratory carrier is 7 below the platen scale and consequently thecarrier has-to be raised or moved a considerable distance to bring {theribbon over the printing point. l urtherm'ore, the weight of thevibratory carrier and other parts is as a rule to be lifted by thefinger of the operator, thereby adding to the heaviness of the touch. Byemploying my invention these disadvantages arevto a large extent doneaway with, the printing portion of the ribbon may be normally arrangedas close as possible to the printing point thus minimizing the extent ofmovement or throw of the carrier, and furthermore instead of having tolift the weight of said carrier it need be 'only moved or swung sidewiseon its pivot.

l urthermore, when a two-color ribbon 1s em ployed it is possible to usea narrow width of ribbon and still avoid any danger of encroaching uponone of the ribbon fields when printing from the other ribbon field. Thisdefect is found in two-color ribbon mechanisms heretofore employed andis especially diflicult to avoid with long characters such.

objects of my invention to avoid this defect and provide a constructionwherein the longi tudinal stripe or stripes of the printin portion ofthe ribbon run or are dispose parallel with the length 0; the type whenthe latter is in the printing position, so that no matter how long thecharacter may be it does not encroach on theotheradjacentfield which is,of course, atone side or the other of the character being impressed,instead of above or below said character as heretofore.

Various other changes may be madewithout departing from the spirit andscope of my invention.
